Amazon adds 15 cities to Sunday delivery

NEW YORK -- Amazon is expanding its Sunday package delivery service to 15 more cities across the country, including Columbus and Cincinnati.

Amazon first rolled out the service as part of a new deal with the U.S. Postal Service in November to New York and Los Angeles, just ahead of the holiday rush. At the time, it said it planned to extend it to other cities this year.

Sunday delivery is available to Amazon customers for no extra charge. If it is available in a customers' region, notice of the service will appear at checkout.

The cities that Sunday delivery is expanding to are: Indianapolis; Lexington and Louisville, Kentucky; New Orleans and Shreveport, Louisiana; Cincinnati and Columbus, Ohio; Oklahoma City; Philadelphia; Dallas, Houston, San Antonio, Austin, Waco and College Station, Texas.
